Bitwig is still beta-testing, Ableton has made a smart move, announcing the long waited release of Ableton Live 9 and offering a discount for Live 8 + free upgrade to 9th version upon it's release. I decided not to wait and ordered it on spot.
It appears I finally have got all the legit software for working on my live performance as well as a great platform for experimenting with new tracks.
The only thing left now are some cables and a decent laptop for running all this stuff when not at home. I wanted to check out Windows 8 to see if it would really make my old Vista laptop less sluggish, but MicroSoft fails to sell the upgrade for Latvian billing addresses, so no luck there yet.
But at least in home environment I've got everything I need to start preparing and learning to play Live+Reason by MIDI controls fluently.
